Hot and muggy, steamy, sultry, sticky or humid. Take your pick, as we are in for a week of the most normcore mid-July weather there ever was. Listless and weak high pressure systems will battle it out with dissipating cold fronts the next few days, giving us the weather you pretty much expect for mid-summer.
Today will be the coolest and driest day of the lot, with a high edging up toward the mid 80s and dew points in the upper 60s. We could see a stray shower or thunderstorm this evening but the bulk of that activity should be up in Orange County as a weak trough passes north of the city. The temperature and dew point will both inch up by a couple of degrees tomorrow, but without any passing disturbances there will only be a slight chance of showers or thunderstorms.
It looks like the dew point temperature will creep into the lower 70s by Wednesday. Combine that humidity with a high near 90 and you have a pretty uncomfortable day with another slight chance of showery activity. The humidity may back off a bit on Thursday as the wind comes out of a more southwesterly direction but that means plenty of sun and a high in the lower 90s. A cold front is expected to arrive Thursday night which should lead to noticeably drier air for Friday and Saturday, but it will still be plenty warm with highs in the mid to upper 80s.
